<p>The roll-up type miniature mosquito-net can be stored unseen in an n-shaped housing (h) with a front (g) and two side flaps (f) shutting off its front. The net guide arms (a) are fixed horizontally to the inside of the side flaps. A bar (b) rolls out along the arms from the housing, the net (d) being secured to the bar by snap-connectors (e), and by similar connectors or magnets to the bottom horizontal plank in the housing. The net is rolled up onto the bar, onto which it is guided by discs (c) at the ends of the latter. The guide arms can be of square, rectangular, U-, j- or C-section.</p> |
